Application of HPMCAS-coated Ctx(Ile21)-Ha peptide microparticles as a potential use to prevent systemic infection caused by Salmonella Enteritidis in poultry

Randomly distributed 40 laying hen chicks per group, including control group A (no Ctx(Ile21)-Ha; n=40), B (2.5 mg of Ctx(Ile21)-Ha/kg; n=40), and C (5 mg of Ctx(Ile21)-Ha/kg; n=40) were performed. Laying hen chicks were orally infected with 0.2 mL (108 CFU/mL) of S. Enteritidis.
